Abstract
An image processing apparatus for forming an image by superimposing n (n≥2) records on a same region in a recording medium includes: a holding unit configured to hold a threshold matrix characteristic representing a dispersity of a dot pattern of each tone obtained when dithering is performed using a threshold matrix; a setting unit configured to set recording data for n recording scans by dividing image data for the n recording scans based on the threshold matrix characteristic; and a halftoning unit configured to perform dithering using the threshold matrix on the recording data for each of the n records.
Claims20
An image processing apparatus for forming an image by superimposing n (n≥2) records on a same region in a recording medium, the image processing apparatus comprising:
- a holding unit configured to hold threshold matrix information related to a threshold matrix characteristic representing a dispersity of a dot pattern of each tone value obtained when dithering is performed using a threshold matrix;
- a setting unit configured to set recording data indicating an amount of recording for n recording scans by dividing image data for the n recording scans based on the threshold matrix information;
- and
- a halftoning unit configured to perform dithering using the threshold matrix on the recording data for each of the n records.
A non-transitory computer-readable storage medium storing a program to cause a computer to perform an image processing method for an image processing apparatus to form an image by superimposing n (n≥2) records on a same region in a recording medium, the method comprising:
- holding threshold matrix information related to a threshold matrix characteristic representing a dispersity of a dot pattern of each tone obtained when dithering is performed using a threshold matrix;
- setting recording data for n recording scans by dividing image data for the n recording scans based on the threshold matrix information;
- and
- performing dithering using the threshold matrix on the recording data for each of the n records.
